Hi Subbu,
 
Glad to hear some interest.
 
You'll need a parallel LCD with HD44780 driver. I've set it up to use 4 bit parallel mode as I didn't have enough spare pins for anything else.
 
Pretty busy just now but I'll get the code to you when I have time and also a schematic.
 
Regards
 
Jamie

Hi Folks,
 
Home again - so if anyone wants a kit please let me know this week.
 
Subbu,
 
Sorry for the delay. Please find the pinout below - but crosscheck it with the particular HD44780 LCD that you get, the below is quite standard but not 100% in my limited experience. I've noticed that Pin3 on the LCD varies a bit. From memory I think Pin3 and Pin15 can be used to vary the contrast and brightness.
 
LCD Pin Description Board Pin Micro Pin
1 GND    
2 +5V    
3 GND    
4 Register Select SW3 13 (PB1)
5 R/W SW5 14 (PB2)
6 Enable SW7 15 (PB3)
7 NC    
8 NC    
9 NC    
10 NC    
11 DB4 LED1 16 (PB4)
12 DB5 LED3 17 (PB5)
13 DB6 LED5 18 (PB6)
14 DB7 LED7 19 (PB7)
15 +5V (    
16 GND    
  Source Select SW SW1 12 (PB0)
 
Code/hex to follow!
 
Cheers
 
Jamie

Howdy folks,
 
I'm  home at the moment, if anyone wants a kit let me know within the next 24 hours!!  I'm testing the LCD firmware a bit more just now, it looks pretty good so I think I'm going to release it.
 
I also made a power supply control board which makes the LED on my on/off switch sleep like an apple LED and controls some relays. Remains to be seen what kind of audio performance will result from using relays however.
 
Cheers

Dear Jambo,
 
I have been trying to get the WM8805 working in hardware mode to connect it to a TDA1541(A) using SPDIF as input.
I have trouble getting it into I2S 16 bit mode (in hardware mode).
If you could provide me with a schematic with your solution, I would be very greatful.
 
Kind regards,
 
Hugo
